Every alchemy recipe on the market, priced from live orders. Profit is per craft, after resource returns, station fee and premium market tax.
Sell now fills the best buy order in that city today. If patient places a sell order at the current lowest listing and pays the 2.5% setup fee; it only pays out once someone buys.
Inputs are bought from the cheapest city. The alchemy city is the one with the highest return rate for that item. Recipes with any missing or stale price are left out, never estimated.
Prices more than three times off their weekly average are hidden by default. They are usually single bait or troll listings.
